1. A method comprising:

  • sensing an acoustic signal using a microphone in a hearing assistance device;

    producing an electrical signal representative of the acoustic signal using the microphone;

    processing the electrical signal using a signal processor in the hearing assistance device;

    detecting a presence of a magnetic field at a programmable threshold produced by a voice communication device using a magnetic sensor disposed in the hearing assistance device;

    in response to the detection of the presence of the magnetic field, automatically modifying the processing of the electrical signal by the signal processor conforming to a prescription target; and

    in response to the magnetic sensor determining removal of the magnetic field, further automatically modifying the processing of the electrical signal by the signal processor.
